What kind of wood do you re deck your trailers with?

My 16 and 18' flatbed trailers both have wood rotting out. I was curious if you go ahead and replace it with treated 2x or if there is a cheaper alternative. Here some trailer places call it "white wood". Not sure what species that term would encompass. Any ideas or luck you have had?

Needs to be lumber 2 X 6 or 2 x 8 or 2 x 10. Decking will not work, to thin. If you have a saw mill close by, go get rough cut 2 x 8 oak, and treat it with some weather sealer before installing. It will outlast the treated pine at the box stores. If you don't have a mill around, then use the treated boards. If you take care of them, they will both last a long time. The non treated wood at the box stores, might last 4 - 5 years tops.

That plastic lumber is too heavy I looked into it for a truck deck its heavier than steel.

Treated 2x6 is probably the best you can use and slather the crap out the end cuts with that juice. You can get treated that is brown over the usual green.

You also would want to buy the lumber then put it somewhere dry stack it up with wood spacers. Let it dry for a week maybe 2. Around here lumber yards sell treated wood that is outside so its heavy and wet you try use it you will have shrinkage between the boards.
